Delta Tecnic recommends the use of masterbatches to companies in the market to guarantee a perfect regularity of the desired color in polyvinyl chloride (PVC) films.
Delta Tecnic has an expertise in PVC coloring, which can be done with pigments that require a lot of cleaning, or with masterbatches: plastic-coated pigment concentrates that do not foul the mixing zones.
Reproducible Color Development
Through the company's range of products, calendaring companies can produce
PVC film more efficiently and cleanlier by means of simplified and reproducible color development between different productions.
Film replenishment of certain items must be homogeneous to produce a high-quality image in the market. There are a variety of applications in this regard, whether it be films for waterproofing buildings, floors, window frames, swimming pools, large format advertisement films or automobiles. In all these cases,
PVC films require high color consistency.
Advantages of Monopigment Masterbatches
In the market, one can find companies that need hundreds of colors for several short production runs. If a company, for example, requires the formulation of 800 colors per year, it clearly does not make sense to demand those many masterbatch references.
In this case, monopigment masterbatches are the best solution, as a small amount of resources can be used to solve an infinite number of final colors. These single-pigment masterbatches offer an excellent dilution during the calendering process and a perfect dispersion that facilitates color consistency between productions.
Manufacturing of Masterbatch
Based on Delta Tecnic's technological innovation, this type of masterbatch is manufactured in a powder-like format through a special milling process using cryogenic mills. The application of liquid nitrogen in the pellet cutting process allows for the creation of cryopellets, which do not melt when subjected to high temperatures during the milling phase.
The excellent dispersion of the pigments used during masterbatch processing leads to the elimination of possible spots or surface defects during the extrusion or calendering processes. This helps to replicate the exact color in each run, something impossible to achieve using pure pigments, minimizing invalid results and the production of non-conforming product due to re-adjustments at the beginning of the production of the colored sheet.
Reduced Cleaning Time
The use of masterbatches reduces the time required for cleaning the mixing units by up to 80%, providing a clear competitive advantage and boosting operational and energy efficiency.
There are some companies that need to produce fewer colors, but in very long runs. In this case, Delta Tecnic recommends the purchase of masterbatch references, capable of directly obtaining the final color desired by its customers, so that with just a few masterbatch references all colors can be covered without the need to use pigments, which, apart from dirtying the installations, the turbomixing and the feeding tubes, do not ensure color regularity between different productions of the same product.
